5.2-RC ataraid woes

[Tomi Vainio - Sun Finland]

Hi,

This is exactly the same problem I see with my system.  Promise
PDC20267 is causing these "READ_DMA recovered from missing interrupt"
-problems but only on secondary channel.  Please try to run
atacontrol pio4 3 if your problem goes away.  This could finally prove
that something s*cks on Promise chip or code for it.
